Introduction (This introduction is not a part of IEEE Std 420-2001, IEEE Standard for the Design and Qualifi cation of Class 1E Control Boards, Panels, and Racks Used in Nuclear Power Generatin

25、g Stations.) IEEE Std 420 was originally prepared in 1973 and revised in 1982 by the Power Generation Committee of the IEEE Power Engineering Society. Based on the activities and scope of that Committee and those of the IEEE Nuclear Power Engineering Committee (NPEC), in 1994 the responsibility for

26、the standard was transferred to NPEC, specifi cally to NPEC Subcommittee 6, Working Group 6.5. IEEE Std 420-2001 provides the requirements for the design, manufacture, and qualifi cation of Class 1E control boards, panels, and racks. It may also serve for modifi cations to control boards, panels, an

27、d racks installed in existing plants. This standard is not intended to defi ne the selection, design, or qualifi cation of piping, modules, or other equipment mounted on the Class 1E control boards, panels, or racks. However, it is concerned with the eff ect that such mounted equipment has on the de

28、sign and qualifi cation of Class 1E control boards, panels, or racks. The selection, design, and qualifi cation of piping, modules, and other equipment are covered by other standards. The purpose of this revision, IEEE Std 420-2001, is to address the following: a)Separation requirements as related t

29、o the requirements of ANSI/IEEE Std 384-1992a b)References as listed in ANSI/IEEE Std 420-1982 c)Comments received on ANSI/IEEE Std 420-1982 The separation criteria contained in ANSI/IEEE Std 384-1992 were used in the preparation of this revision, IEEE Std 420-2001. It is the intent of the Working G

30、roup that these two documents be consistent. The Working Group received comments regarding the need for specifi c separation requirements for fi ber-optic cabling. Until further guidance is provided, separation requirements for fi ber-optic cabling should be in accordance with ANSI/IEEE Std 384-1992

31、. The qualifi cation of Class 1E control boards, panels, and racks is included in this standard to address the overall requirements of ANSI/IEEE Std 323-1983 and ANSI/IEEE Std 344-1987. The qualifi cation areas covered consist mainly of environmental and seismic requirements that specifi cally relat

32、e to control boards, panels, and racks. Other IEEE standards have been referenced as necessary to provide applicable qualifi cation information, such as aging methodology. One of the issues discussed by the Working Group was that of commercial grade dedication. After much discussion, it was agreed t

33、hat there is nothing unique about the commercial grade dedication process as it applies to the design and qualifi cation of control boards, panels, and racks. Therefore, no reference to this process is included in the body of the standard. Copyright ? 2002 IEEE. All rights reserved.iii aInformation
